Re: All Versions of LC crashing in Sonoma

[Tore Nilsen via use-livecode]

LiveCode 9.6.9 Build 15604 works in Sonoma, the same goes for LiveCode 10 DP6. 
Try to download 9.6.9 again, you may have an older build of 9.6.9.

Re: JSON

[Tore Nilsen via use-livecode]

An array of object would be turned into a multidimensional  array with value 
pairs in LiveCode. Depending on the source the main keys may be numeric or 
assosiative, like in these examples:

contriesArray[1][name]
contriesArray[1][capitol]
contriesArray[1][inhabitants]

Or 

contriesArray[«Norway"][capitol]
contriesArray[«Norway»][inhabitants]

What is «puzzling» to me, among a whole lot of other things I fail to grasp, is 
why in the first example, the value in field «test» is treated as a single 
parameter, but in the last example it is treated as five parameters, since 
nothing has changed with the values in the field itself. I do however accept 
the reality of it, but I wanted to understand why this is the way it is. My 
original thinking was that by referencing the field as parameter, the values of 
the field would then become de facto parameters passed on to the function. I 
guess it is just another item in the long list of things I do not fully 
understand. :-)

Field content as parametres in a function

[Tore Nilsen via use-livecode]

I have come across a puzzling behavior when trying to use the content of a 
field as parametres in a function, and I am trying to understand why.

I put the following in a field called «test»: 1,2,3,4,5

When I then call the function like this:  
answer testFunction(field «test»), the paramCount() returns 1

If I use the values directly in the script: 
answer testFunction(1,2,3,4,5), the paramCount() returns 5 as 
expected

I will also get the expected result if a do the following:

put "answer testFunction(" & field «test»  & ")" into tScript
do tScript

I guess the reason for this is that in the last example, LiveCode compiles the 
content of the variable tScript before execution, and that this turns what is 
first treated as a single block of text into a list of parametres. 

The reason why I want to understand what is happening is that I am about to 
teach my students how to write reusable code that will behave correctly for any 
number of parametres. 

So my question is if I am on the right track?

Best regards
Tore Nilsen

Re: What is the best way to trigger an action at a certain time?

[Tore Nilsen via use-livecode]

For this I would use a recursive approach with «send in time» something like 
this:

checkTime
end openStack

on checkTime
  ## Do your routines of checking time, performing the required action etc.
  send checkTime to me in 300 seconds. ## you set the interval to whatever is 
best for you
end checkTime

Re: Set HTMLText and Get Effective HTMLText

I would think it is because the htmlText is a property of a field. It is one of

How to paste into a form element in the browser widget

[Tore Nilsen via use-livecode]

I have a problem pasting into a form element on a web page in the browser 
widget. This works well in the IDE, but not in a standalone application. The 
application has no menus, but I have included a pasteKey script to handle paste 
shortcuts. This does not seem to do the trick in the browser widget. I have 
tried to put the script in the stack script, the card script and even in the 
widget itself, although I wouldn’t expect the latter to work. Are there anyone 
who has run across this problem before and may offer a solution?

Re: PDF Widget

[Tore Nilsen via use-livecode]

Not everyone needs it. I had the business edition for a year and for what it is 
worth, the pdf-widget did not offer anything I needed. I had hoped I could use 
it for mark up and annotations but did not find a way to do that.

I do however think that it would be a good thing if it was possible to buy 
widgets on a per widget basis. That would enhance the LiveCode experience in my 
mind.

Re: Checking the Milliseconds

[Tore Nilsen via use-livecode]

It averages around 3850 and 3900 every time I try. However, when I try to run 
the test 1 times the average goes down to just above 3600.

I haven’t tried on a machine where I am not the owner. This may be why it 
worked. When I come to think of it I am not certain I have been writing to the 
resource folder in any of the apps I have given my students, but I am quite 
certain I have read from such files.

I set up an application with the following code in the  stack script:

on preOpenStack
   put specialFolderPath("resources")& "/testfolder/" into tURL
   create folder tURL
end preOpenStack

In the script of a button I put the following:

on mouseUp

ask "Write something to go into the resource folder:"

put it into tText

put "file:" & specialFolderPath("resources") & "/testfolder/test.txt" into tURL

put url tURL into tData

put tText & return after tData

put textEncode(tData,"UTF-8") into url tURLanswer url tURL

end mouseUp


I then build a standalone for Mac and started the application. After running 
the script from the button three times I did find the file test.txt in the 
folder named «testfolder» inside the _MacOS folder in the contents folder of 
the app bundle. The file contained the exact three lines I had written. Whether 
or not this will work on windows I don’t know as I do not have any computer 
running Windows to try it on.

I just made a test application where I am able to create a folder in the 
resources folder on preOpenStack. I then am able to read from and write to a 
document in this folder without any problem. This is on macOS Big Sur. The path 
to my folder in the resources folder in the app bundle is 
«Contents/_MacOS/testfolder/« and the application can write to this folder 
without any questions about permissions.

To the best of my knowledge, I think this is wrong. In MacOS the resources 
folder is part of the application bundle and resides within the content folder 
in that bundle. I have never encountered any problem with this folder even when 
using un-notarized and unsigned apps. I give away small apps to my students 
(both Mac and Windows) all the time and I use resources, desktop and documents 
as the main folders to write to and read from. All of these folders work OK. 
The user will be asked if they want to give the application permission to 
access these folders, but other than that I don’t know of any hiccups. 

I know that there are several restrictions when you deploy to various mobile 
platforms. These are explained in the Dictionary.

 Quick question. Why would the line number field be complicated? I

Since the properties of the arc is available even if it is invisible, this will 
work though:

on mouseDown

put isWithin("myGraphic",the clickLoc)

end mouseDown


function isWithin pGraphic pClickLoc

if pClickLoc is within the rect of grc pGraphic then

return true

else

return false

end if

end isWithin

Re: LC Roadmap

[Tore Nilsen via use-livecode]

I am currently working as a teacher in an upper secondary school in Norway. I 
teach Computer Science and languages like English and Norwegian. Besides 
working as a teacher for more than 20 years, I have also experience from 
running various businesses. The combination of the two very different, but also 
in some parts, very common experiences, forms the basis of my thoughts on this 
topic.

From being in charge of running a business with about 20 employees and more 
than 100 recurring customers, I have learnt the importance of due diligence in 
all aspects of running the business. Whenever I was about to make a promise to 
a customer, I alone was responsible for making sure I could keep this promise. 
If the job at hand required new tools, I would never commit to the task before 
I actually had said tool at my disposal. Sure enough, I could find vendors who 
would promise to deliver on time, but to me such promises are nothing more than 
a good intention.

I look at the LC Roadmap in very much the same way. As a teacher I think I 
understand why the LC Roadmap is not a reliable tool to use for planning future 
solutions. As a teacher I am supposed to make plans in advance. I should make a 
plan for the whole of the school year, and a plan for each semester, the latter 
more detailed than the first. They are very much like the roadmap or the 
promises from vendors.

In reality these plans are not worth the bytes they occupy on the server. To be 
honest, even the plans I just made for next week and for each lesson next week, 
will fail one way or another. Such is the nature of plans vs. reality. And it 
is not about me or anyone else not caring about fulfilling the promises of the 
plans. It is simply because I am not able to control every variable that will 
affect the work we do.

As developers it should not be difficult for us to understand that a roadmap is 
just an expression of what LC Ltd  hopes to achieve within a given timeframe. 
It should not be considered to be a solid basis for making future promises to 
our customers. If we choose to do so, it would be just as stupid as if I chose 
to press on with my plans for this week, without any consideration to what 
happened in the classroom last week. And the responsibility would be with us, 
not the plans or the roadmaps.

On the question on whether or not the LC Roadmap should be updated, the answer 
is of course, yes. All plans that are outdated should be updated. But the new 
plans should be treated with the same amount of caution as the previous ones. 
Especially so if our livelihood depends on how we treat these roadmaps.

Re: Close Stack Cleanup

[Tore Nilsen via use-livecode]

Performing the clean up in preOpenStack makes it happen before the stack is 
visible, at least according to the dictionary.

"Unlike openStack <>, preOpenStack handlers <> are executed <> before the stack 
window <> appears. Because of this, the preOpenStack handler <> is a good place 
to put code that adjusts the size, position, and appearance of objects <>; the 
changes are made before the stack <> appears."

My experience is that this is true.

Re: Close Stack Cleanup

[Tore Nilsen via use-livecode]

I follow a similar approach to what Curry describes here, keeping it modular, 
but I do not do any clean up at closing time. Instead I execute the necessary 
routines as part of a preOpenStack handler. I then do not have to consider 
which way the stack was closed. This is also what I encourage my students to 
do, in order to present the users with a pristine application every time the 
user starts the application.

By keeping it modular, the clean up script can also be started from other 
handlers if necessary. 

Best regards
Tore Nilsen

 LockScreen commands are queued. So if you lock the screen twice, you have 
 to explicitly unlock twice in order to clear the locked state.
 
 It does not matter what happens in the flow of code in terms of screen 
 locking, whether other command or function calls are made. The queue rules

Re: lock screen

[Tore Nilsen via use-livecode]

The browser widget is drawn in a layer of its own and is not affected by lock 
screen. If you need to do a visual effect you then hide the widget itself and 
perform the visual effect on the snapshot. You can then delete the snapshot 
when it is no longer needed.

One could think that the grid snap feature would work in Run mode in the IDE if 
scripts would allow the user to move controls in this mode. One could also 
think that the grid snap feature would work in a standalone under the same 
circumstances. This would allow for better control of placement of controls 
«out of the box».

I can happily build a MacOS app without code signing or notarizing the app from

And if you have a multiline field and would like to go to the end of the 
current line use this:

on rawKeyDown theKey

if theKey = 65367 then

put word 2 of the selectedLine of me into tLine

select after line tLine of me

else

pass rawKeyDown

end if

end rawKeyDown

You could try this in the field script:

on rawKeyDown theKey
   if theKey = 65367 then
  select after me
   else
  pass rawKeyDown
  end if
end rawKeyDown

This will allow the normal behavior for all other keys when the field is active.

Re: Audio recording in LC community on Windows?

[Tore Nilsen via use-livecode]

Feature parity between Mac and Windows is a necessity for me as well. I teach 
at an upper secondary school (high school) in Norway, and we are obliged to use 
software that supports both platforms, as students bring their own computers 
and should not be required to install two OS-es to do their work. I think a 
request for feature parity would be in its place.

Re: Is the DateFormat read only?

[Tore Nilsen via use-livecode]

You can convert any given date to dateItems. Then you can use dateItems to 
present the date in any format you like. A date converted to dateItems will 
give you the following list of items: 

the year
the month number
the day of the month
the hour in 24-hour time
the minute
the second
the numeric day of the week where Sunday is day 1, Monday is day 2, and so forth
All according to the Dictionary.

To be sure that any valid date format is recognized as a date when you read in 
the date you will like to convert, it is best to ask for the system date or set 
the useSystemDate to true, as this will make all valid date formats convert to 
dateItems.

Best regards

Re: How to divide card with/in 3 vertical lines?

[Tore Nilsen via use-livecode]

You could of course also multiply the width of the card with 0.25, 0.5 and 0.75 
to get the same results. Personally I prefer multiplication to division, but 
the results will be the same.

In the url itself you use access_token but in your search you use access_code.

Re: backKey with DataGrid

[Tore Nilsen via use-livecode]

This is a shot in the dark but this may have to do with the fact that once the 
dataGrid is in focus the template stack for the dataGrid becomes the recipient 
of your backKey message. Have you tried to add a backKey message to the 
template stack, and tweaking it to reference the button of the card in the 
original stack?

Re: Wrapping Text

[Tore Nilsen via use-livecode]

In order for this to work you should also take into consideration various rules 
for hyphenating words in the appropriate language. As these rules varies 
between languages, this can become a very complex function. If the text that 
goes into the field is static then I would either reduce the font size, widen 
the field (or both) or try to find a synonym that fits into the width of the 
field.

 Hi.
 
 Sorry, it is "dontWrap", not "donttWrap".
 The field is not truncating, except visually. The text runs out the right 
 side of the field's visible extent. Setting the "dontWrap" to false will 
 force the field to wrap the text.

 You must remember that this is not the same as adding carriage returns in

Re: [off-topic-ish] do you prefer LC-related content as books or video courses?

[Tore Nilsen via use-livecode]

Hi Andre!

As others have pointed out, whether to go for a text based or a video based 
course, very much depends on your target audience. I like Richards proposal of 
using LiveCode as the framework for a course. This way you can in fact utilize 
the strengths of both formats. You can present most of the course as text, and 
with a good search function and a good index, it can in many ways work better 
than a traditional printed text.

The real benefit is that you can also add video wherever this will provide an 
added value. If the course are a beginners course, video can work well when you 
demonstrate how to use the IDE and how to build a UI for an application. 
Remember that shorter videos are better. Also, video works best for 
demonstration of concrete actions. You can further enhance the effect of being 
able to use both text and video by adding each step of the video as text as 
well.

If you are to show script as video, remember to give the viewer plenty of time 
to study each line of code. I find that when I show my students something on 
the whiteboard, they very often think that I am to quick, and that I move along 
to fast. It is also advisable to keep the screen as clutter free as possible, 
only show code that is part of the command/function you are writing at the 
moment. If the students get lost during the presentation, it is very hard for 
them to get back on the right track (or line as it were) if they have to 
distinguish between different parts of your code.These are hard learned facts 
after teaching high school students how to use LiveCode in computer science 
classes for the last seven years. 

Just as important as the format you choose to deliver your course are the 
content of your course. From my experience as a teacher I would suggest that 
you distinguish basic skills from intermediate and advanced skills. I have run 
into trouble trying to rush things in my classes from time to time.

Best wishes and best of luck.
Tore

[Tore Nilsen via use-livecode]

Sorry for asking you to do something you had already tried. I see now that you 
indeed tried setting the url of the widget. I just presumed that it worked the 
same way in iOS as in Win and MacOS. I do not develop for mobile so I have 
never had to deal with the way Android and iOS handles these things.

Re: Browser Widget iOS Local Html Files

Have you tried to set the url of the widget to tTemp. This actually loads the 
page in the widget as if it was any browser.

Re: HTML Colour Groups

[Tore Nilsen via use-livecode]

You try to sign a value to tColor with the command set. The right command is 
put, as in this example, this works on my end:
put "#FFC0CB" into tColor

set the backgroundcolor of graphic 1 to tColor

Re: Changing text properties in a field via the IDE

[Tore Nilsen via use-livecode]

I am not sure this is a bug. When you use the normal paste function you 
actually paste in styled text. New text, following the text you pasted in will 
inherit the styling of the last character of the text you pasted into the 
field. This then would work the same way as if you selected some text in the 
field and altered the styling of this selected text. All unselected text would 
adhere to the properties set in the Inspector. In my opinion this is what you 
would expect from any text editor. If you would like to paste in some text 
without the styling you should use «Paste Unformatted» in the IDE.

Re: Dark Mode Detection

[Tore Nilsen via use-livecode]

I guess it means that you can make an application that detects whether or not 
the user system is running in dark mode and write your own code to set the 
properties of your application accordingly. It means that you can write 
applications that are aware of the mode on the user system.

Re: Building a Board Game

[Tore Nilsen via use-livecode]

What I do is to make a grid of named rectangles (they may or may not be 
visible). I put the names of these into a variable or an array. On mouseUp I 
traverse the variabel/array to check if the mouseLoc is within any of the 
rectangles. When there is a match I set the loc of the grabbed control to the 
loc of the matching rectangle.

Re: Ordering text

[Tore Nilsen via use-livecode]

I believe the reason for the delay comes from the fact that when sorted 
descending, you put tRec & CR before tCellData. Tp put something before a 
container is slower than putting something after a container.

The problem here is that when a group is set to behave as a menubar on MacOS, 
the target becomes the group and not any of the individual buttons. Therefore 
the script as it is written in the tutorial will not work, since the update of 
the menu will only happen if the short name of the target is «window». It will 
work if you remove the encapsulating if-statement.

Removing the if-statement will update the content of the «Window» menu 
regardless of which menu you choose, provided that the script is placed in the 
group script. This way the user may well choose another menu initially, slide 
to the «Window» menu and be presented with an updated menu. So, while this may 
be a bug, the way around it is to write less code. If only all problems could 
be solved this way.

I haven’t used callbacks much, and so far I haven’t run in to any problems. If 
missing callbacks is still an issue, then I agree with you that setting 
startTime and endTime is the best option. I use this method in a small 
application I have made for myself where I write comments to audio files handed 
in by my English students. They can then control playback of the segments I 
have commented on by clicking links in the field that shows the comments. The 
lack of audio recording capability on Mac has forced me to use written feedback 
where I otherwise would have preferred using two players and audio feedback.

Regards
Tore

Re: Synchronisation of sound and vision

[Tore Nilsen via use-livecode]

Using callbacks negate the need to fiddle with duration or  timescales and 
start or stop times. It uses the sampling intervals as is, regardless of time. 
In my opinion it is much easier than trying to calculate start and end times. 
You can easily handle large audio/video files using callbacks. I would 
recommend using one file per poem though, this simplifies the handling of the 
messages sent from the player. You can basically use the same message for all 
files, resetting a counter variable each time you load a new file to handle 
with line you would like to act upon.

You could also store the callbacks for each audio file in a text file and set 
the callbacks as a part of the handler used to load each audio file.

Re: Synchronisation of sound and vision

[Tore Nilsen via use-livecode]

Yes, you have to manually set the callbacks. I would opt for lines rather than 
words. You get the callback points by getting the currentTime property from the 
player. If you start at the beginning you can set the first item of the first 
line of the callbacks to: 0. Then you can set a callback for each line in the 
poem by pausing the player after each line and get the currentTime of the 
player. This could be semi automated with a script that is triggered each time 
you pause the player, I guess.

Re: Synchronisation of sound and vision

[Tore Nilsen via use-livecode]

You will have to use the callbacks property of the player to do what you want 
to do. The callbacks list would be your cues. From the dictionary:

The callbacks of a player <> is a list of callbacks, one per line. Each 
callback consists of an interval number, a comma, and a message <> name.

Re: Option menu in datagrid

[Tore Nilsen via use-livecode]

You can also set the text of the button in a mouseDown handler in the button 
itself. This works well if you have more than one option menu and the options 
in one of them depends on the selections the user has made in another. The 
script will be similar to the one provided by Sri.

Re: Something wrong with LiveCode 9.5.1

[Tore Nilsen via use-livecode]

This is not very odd. It is the way MacOs now handles all applications that are 
not notarized. I would suspect this kind of message for any dp or rc version of 
LiveCode, but not for a stable version. You can get around this either by 
right-clicking the application and choose «Open»  from the local menu. You will 
then have an option to choose to open this application. Once you have done, the 
message will not reappear when you start LiveCode.

Map widget and user location

[Tore Nilsen via use-livecode]

I am trying to familiarise myself with the map widget. What I want to do is to 
get the coordinates for the user location and to set a pin for this location. 
As it is possible to show the user location in the map widget, my original idea 
was to retrieve the information from the widget and apply it to a marker in a 
mouseUp handler. 

If anyone could point me in the right direction I would be a very happy man.

Re: Primary Student Livecode Interface (Simplified Developer Interface)

[Tore Nilsen via use-livecode]

Hi!

I teach a beginners course in programming on highschool level in Norway. Just 
like Devin, I have found that the most important thing is what you want your 
students to learn. The development environment is not very important. I try to 
introduce various components in a way that helps build the students 
understanding of the fundamental concepts and principles used in programming.

I use a methodology quite similar to the one Devin suggests at the end of his 
reply. 

1. I present and show my students a concept/principles/method
2. We use this concept on various simple problems together in the class - this 
will often be accompanied by classroom discussion
3. The students then get a task where they can apply the concept on a problem 
that is quite similar to the problems used in point 1 and 2
4. Then I give my students a task which involves a more complex problem, where 
the application of the concept is not very obvious. At this point I encourage 
my students to help each other with the task.
5. The students then show their various attempts at solving the problem, either 
to a group of students or the whole class, and we discuss the various solutions 
in class
6. If needed I will then show them examples of «best practises». Here I will 
also present various controls and how they can be used as part of the solution 
of the given problem

At the moment we are setting up the classroom to facilitate this approach in a 
better way. The classroom is divided into five groups, each group having its 
own large table with a 42 inch monitor, that all students can connect to, at 
the end of the table. We are about to set up a solution with HDMI Matrix 
Switches that will allow each student to route their screen to any of the 
monitors and to the main projector if needed. Likewise, I can share my screen 
with any of the monitors or the main projector. This will help my students in 
sharing their solutions/problems with each other.

Like Devin, I have also come across research that seems to indicate that 
drilling is better than complex problem solving in teaching basic skills. 
However, my experience is that to much of this will make it harder for my 
students to become good problem solvers. In my course, all students must 
develop an application of their own choosing, from initial idea to finished 
product, in the last term. Many of my students have indicated that this have 
been the most important factor in the development of both understanding of and 
skills in programming. I think that the most important factor in this is the 
kind of problem the students face in step 4 of this method. This problem most 
be near enough to the original problem, but still different from it. This 
decides the quality of the discussions we get after the students have tried to 
solve the problem.

Best regards
Tore Nilsen

Re: Catalina

This is easily remedied. Just choose LC 9 in the Finder, choose Show Info and 
make sure you run it in 64 bit mode. I don’t have an English OS setup right 
know, but you should opt out of running the application in what in Norwegian is 
called "low resolution mode". Once you do, you will not get these warnings 
anymore.

of the url of a browser widget when i set the url from a script using «answer 
file» to navigate to any valid html file:

on mouseUp

answer file "Choose html file to display"

set url of widget "browser" to it

end mouseUp

Re: how to load a local file into the browser widget?

[Tore Nilsen via use-livecode]

You must make sure that the filePath to the html file you would like to see 
does not contain any invalid characters like spaces, which you will find is OK 
by the file system but not with the browser.

Re: Resizing stacks and make changes on more than one card

Thank you for your suggestions. I did not have any resizeStack handlers, but

send resizeStack to me in a preOpenCard handler on both cards.

Resizing stacks and make changes on more than one card

[Tore Nilsen via use-livecode]

I have a stack with 2 cards. On these cards, some elements change size or 
position when the stack is resized. As the resizeStack message is only sent to 
the current card, any changes only happen on this card. If the user then 
navigates to the other card, elements will be out of order on this card. 

I have tried sending resizeStack to the other card in a resizeStack handler on 
each card, but this only causes a recursion limit error, obviously. I have also 
tried to send  resizeStack before actually navigating to the other card with no 
result.

Do anyone have a solution for this, apart from arranging the elements in an 
openCard handler?

Re: TabStops and Tab Spacings

[Tore Nilsen via use-livecode]

If I understand your question correctly, you would like to export the styled 
text to an external document. If this is the case then you could use this:

Put the rtfText of field myField into url myURL — where the file extension 
should be .rtf. You will then have styled text document where, to the best of 
my knowledge, your tab stops should be preserved.

Re: SVG widget and grab me command

My mistake, I meant handles, not handlers. The widgets are used to display 
chess pieces. The actual script «controlling" each widget/group is a behavior, 
where the script itself resides in a button script.

Re: SVG widget and grab me command

[Tore Nilsen via use-livecode]

Thanks for your explanation. Since my student does not need any handlers (in 
fact would not want any handlers added to the widgets), the examples from 
«ControlHandles89» could not be used.

The simple solution was to «group» each individual SVG widget and add the grab 
me command to the group.

SVG widget and grab me command

[Tore Nilsen via use-livecode]

When one of my students tried to use grab me command in a mouseDown handler on 
a SVG widget, some strange things happened. In run-mode, the script did not 
work as expected. The widget would not move with the mouse. When switching back 
to edit mode, the widget started to move with the mouse once the cursor entered 
the rect of the stack. It was impossible to put down the widget afterwards.

The same thing happened when we tried to make the widget follow the mouse in a 
mouseMove handler. Has anyone else come across this?

Re: Repeat for each line of a variable or field?

[Tore Nilsen via use-livecode]

When using a field with close to 45000 lines, the second (using the lines of 
the field) version takes on average 23 milliseconds, whereas using a variable 
takes on average 15 milliseconds. For a field /variable with 5000 lines  the 
difference is about 2 milliseconds here. The actual speed and difference will 
vary according to your hardware I guess.

Re: LC 9.02 Problems when displaying local PDF in stack

I had the same problem as you, and I used the Adobe Unistaller Program to

done the trick for me at times when I simply cannot find the file(s) causing

Try to remove the Adobe Acrobat (Reader) Plug-in from the Internet Plug-ins

Alternatively you could try to uninstall Acrobat altogether.

You are right, there was this third option prior to High Sierra. I agree that 
if you distribute an application  as a professional developer, you need to code

Re: Seeking OSX Code signing consultant...

[Tore Nilsen via use-livecode]

You can easily run an unsigned app on High Sierra or Mojave. But you can not 
start the application by double clicking it the first time you run it. You need 
to open it from a contextual menu (right click or ctrl click) and then choose 
«Open» in the resulting dialog window. Afterwards you can use the unsigned 
application just as a signed application.

I do this all the time with apps I give to my students

 learning time. Also, we do not develop for iOS nor do we deploy to the Mac 
 App store, so hopefully none of the lessons pertaining to those apply to 
 us.
 
 As stated in my initial email, we develop in LC under Windows. We build 
 standalones for OSX and Window. We want to PAY someone to help us set up 
 code signing under El Capitan (10.11.x) and XCode 8.2.1. I can't imagine 
 that for someone who knows what they are doing it would take more than a 
 couple hours on an online meeting (screen sharing ) with us.
 
 I am astonished there are no takers among the LC community. How about 
 LiveCode Professional Services?

Re: Live Code crashes on startup

[Tore Nilsen via use-livecode]

Hi Camm!
Deleting the preference file worked here as well. We had a problem finding it 
as I use a Mac and neither I nor the student had any idea where to look for 
preference files on Windows. Panos advice helped us along.

Best regards
Tore

Live Code crashes on startup

[Tore Nilsen via use-livecode]

One of my students has a problem with LiveCode crashing on startup. He uses a 
machine running Windows, and I suspect there might be a corrupt preference file 
involved, as LiveCode dies right after it has loaded the preferences. Since I 
have no experience in using LiveCode on Windows, I have not been able to locate 
the preference file. Can anyone point me in the right direction? 

Best regards
Tore Nilsen

Re: Browser widget and PDFs

[Tore Nilsen via use-livecode]

Thank you all for your responses, they helped me solve the problem for my part. 
It is indeed the Adobe web Plugin that is the key to this. Although I have 
never checked that I would like to use this plugin, it seems as if just 
launching Acrobat will do this automatically. In the Acrobat preferences the 
check button for this  is set to true, and the button is disabled. I ended up 
removing Acrobat from the system, but I could probably have followed Hermans 
advice and just remove the plugin from the Internet plains folder.

Now I have to ask my student to do the same in order to have the pdf-files 
displayed without all the bells and whistles provided by the plugin.

Best regards
Tore Nilsen

Re: Browser widget and PDFs

[Tore Nilsen via use-livecode]

I don’t think so, as the default app is set to be Preview on both machines. In 
fact I had forgot I had Acrobat installed on my laptop.

Browser widget and PDFs

[Tore Nilsen via use-livecode]

I have come across a puzzling phenomenon in how the browser widget handles 
pdfs. On my iMac I do no have Adobe Reader or Adobe Acrobat installed. Here, 
the browser widget displays pdf-files without any hiccups. On my MacBook I have 
Adobe Acrobat installed, and the browser widget seems to use Adobe Acrobat to 
display pdf-files inside the widget. When I remove Adobe Acrobat from the 
application folder, trying to view a pdf-file in the browser widget will prompt 
me to locate either Adobe Acrobat or Adobe Reader.

Are there any way I can «force» the widget to ignore Acrobat or Reader 
entirely, and will I be able to view pdf-files in the widget on bothMac and 
Windows if I do so?


Best Regards
Tore Nilsen

Re: Bug in how LC handles sentences

[Tore Nilsen via use-livecode]

After some thinking I actually do agree it is not a bug. The problem being that 
full stop (period) can also be used in abbreviations, and numbers can follow 
immediately after such abbreviations.
